Answer:

  • See below

Step-by-step explanation:

  • Given details help to determine the function only.
  • There is no relationship between the mileage and future cost.
  • We only consider the current price, decay rate and number of years.
<h3>Car A</h3>
  • Cost = 8750
  • Year of Manufacturer = 2015
  • Decay factor = 12% or 0.12

<u>The function would be:</u>

  • f(x) = 8750*(1 - 0.12)^x = 8750*0.88^x, where x is the number of years since year 2015
<h3>Car B</h3>
  • Cost = 9995
  • Year of Manufacturer = 2017
  • Decay factor = 18% or 0.18

<u>The function would be:</u>

  • f(x) = 9995*(1 - 0.18)^x = 9995*0.82^x, where x is the number of years since year 2017

Find the volume of a cone with a height of 7yd and a base diameter of 6yd . use the value 3.14 for π , and do not do any roundin
yarga [219]
I think the volume of the cone is 65.94yd because the radius is 3 and the height is 7 also 3 to the second power equals 9 then 3.14 multiplied by 9 equals 28.26 and finally 28.26 multiplied by 7/3 equals 65.94

V=3.14 x r^2 h/3
V=3.14 x 3^2 7/3

Answer:

  2 1/4 yards above sea level

Step-by-step explanation:

The midpoint elevation is the average of the endpoint elevations, their sum divided by 2. When elevation is below sea level, it is represented by a negative number.

  (17 3/4 - 13 1/4)/2 = (4 2/4)/2 = 2 1/4 . . . yards above sea level
